2 Claims. (01. 22933) I This invention relates to cartons and isdirected more particularly to improvements in a pro- .formed cartonblank arranged and adapted for folding to provide a receptacle.

The principal objects of the invention are the provision of a cartonblank which is constructed and arranged to be readily and easily set upto provide a receptacle which is not only strong and durable but onewhich has a closure adapted for swinging between open and closedposition thereby making the contents of the receptacle accessible whenin open position. At the same time, when the closure is in closedposition the receptacle is adequately closed.

The blank may be made in various sizes and shapes for formingreceptacles for numerous and various purposes and in general is adaptedfor wide uses.

with the foregoing and various other novel features and advantages andother objects of my invention as will become more apparent as thedescription proceeds, the invention consists in certain novel featauresof construction and in the combination and arrangement of parts as willbe hereinafter more particularly pointed out in the claims hereuntoannexed and more fully described and referred to in connection with theaccompanying drawings wherein:

Fig. 1 is a pe ctive view of a receptacle formed according to theinvention;

Fig. 2 is a view similar to that of Fig. l with the closure of thereceptacle in open position; and

Fig. 3 is a plan view of a blank adapted to be formed to provide thereceptacle shown in Figs. 1 and 2.

Referring to the drawings more in detail, the invention will be fullydescribed.

The blank 2 of the invention as shown in Fig. 3 has a bott m wallsection 4 to the longitudinal ed es 6 of which are hinged side walls 8.Inner upper wall sections it are hinged to the longitudinal edges of theside walls 8 as at 12.

Cut-outs i 4 are provided at the outermost edges of the upper wallsections ll.

Outer end walls It are hinged at II to opposite ends of the lower wall 4and pairs of inner end wall sections 20 and 2| are hinged at 22 to theends of the side walls I. p The sections It may be provided withinterlocking notches 2|.

Slots 24 are provided along the lines II for receiving tabs as willappear.

Outer upper wall sections or closures 2i and 21 are hinged at 2| to thesections II and flaps II andl2arehlngedatlltothesections2t.

- 2 Tabs 28 and It are hinged at 40 and 42 to opposite sides of thesections 20 and 22.

The blank may be formed to provide sections oi! various sizes and shapesthereby to form receptacles of various sizes and shapes and said blankmay be formed from cardboard or someother suitable material.

In setting up the blank the side walls 8 are swung upwardly and themembers 2| are swung inwardly with the notches 2 I thereof brought intointerlocking engagement.

Wall I6 is swung upwardly against members 2i, the upper sections i 0 areswung inwardly and end wall it adjacent member 2| is brought downthereover so that member 21 overlies members It and then members 36 areinserted in slots 24.

Then members 20 are swung inwardly and member l6 adjacent thereto isswung upwardly. Members 26 and 32 may be superposed on the upper wallsID to close the carton with members 38 in the slots 24 as shown inFig. 1. Or the parts may assume the open position shown in Fig. 2.

By means of the novel construction closure 32 may be swung from closedto open position so that the contents of the receptacle are accessiblewhile the receptacle is held in shape by the members It, 21, 30 and 36.

The receptacle is adapted for many and various uses and may be made innumerous sizes and shapes.

In some cases the notches 2 i may be eliminated and the members 20 maybe omitted if desired.

The invention may be embodied in other specific forms without departingfrom the essential characteristics thereof. Hence, the presentembodiments are therefore to be considered in all respects merely asbeing illustrative and not as being restrictive, the scope of theinvention being indicated by the appended claims rather than by theforegoing description, and all modifications and variations as fallwithin the meaning and purview and range of equivalency of the appendedclaims are therefore intended to be embraced therein.

What it is desired to claim and secure by Letters Patent of the UnitedStates is:

1. A folding blank for forming into a box comprising, a single sheet ofmaterial having a bottom wall section and side walls hinged at theirlongitudinal edges to longitudinal edges thereof for swinging upwardlyrelative to said bottom walls, inner end members hinged to opposite endof said side walls for swinging inwardly therefrom to form end wallsadjacent said side walls.

inner upper wall members having hinge connecmeagre tions with outerlongitudinal edges of said side walls for swinging inwardly relativethereto into relatively parallel position providing an upper wall, saidhinge connections provided with longitudinal slots terminating inwardlyof opposite ends of said side walls, outer end walls hinged to oppositetransverse ends of said lower wall section for overlying said inner endmembers and having outer upper wall sections hinged thereto foroverlying opposite end portions of said inner upper wall members, flapshinged to said outer upper wall sections for overlying adjacentintermediate portions of said inner upper wall menibers having tabs atopposite sides thereof receivable in said slots for holding said outerupper wall sections and flaps on said inner upper wall members, saidflaps having relatively overlapping portions at ends thereof disposedover intermediate portions of said inner upper wall members.

2. A folding blank for forming into a box comprising, a single sheet ofmaterial having a bottom wall section and side walls hinged at theirlongitudinal edges to longitudinal edges thereof for swinging upwardlyrelative to said bottom wall, inner end members hinged to opposite endsof said side walls for swinging inwardly therefrom to form end wallsadjacent said side walls. inner upper wall members having hingeconnections with outer longitudinal edges of said side walls forswinging inwardly relative thereto into relatively parallel positionproviding an upper wall,

said hinge connections provided with longitudinal slots terminatinginwardly of opposite ends of said side walls. outer end walls hinged toopposite transverse ends of said lower wall section for overlying saidinner end members and having outer upper wall sections hinged theretofor overlying opposite end portions of said inner upper wall members.flaps hinged to said outer upper wall sections for overlying adjacentintermediate portions of said inner upper wall members having tabs atopposite sides thereof receivable in said slots for holding said outerupper wall sections and flaps on said inner upper wall members, saidflaps having relatively overlapping portions at the end thereof anddisposed intermediate portions of said inner upper wall members, andinner portions of said inner upper wall members being cut away adjacentcorresponding ends thereof.
